 » Abstract 

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are associated with kidney damage. In India, only a few reports related to the risk of chronic kidney disease (CKD) with NSAIDs are available. The present study highlights the prevalence and pattern of NSAIDs-induced CKD adverse drug reactions in the Indian population.
MATERIALS AND METHODS: The individual case safety reports (ICSRs) reported by the National Coordination Centre (NCC)-Pharmacovigilance Program of India to the Uppsala monitoring center Pharmacovigilance database system “VigiLyze” were analyzed by using the preferred term “Chronic Kidney Disease” and “NSAIDs” from July 1, 2011 to September 12, 2019. A total of 28 ICSRs of NSAIDs associated CKD ICSRs were analyzed retrospectively for age, gender, concomitant medication, seriousness, and other criteria.
RESULTS: About 82% of CKD cases due to NSAIDs were in the age group of 40–80 years, in which 54% belong to male. About 43% of the patients had CKD due to the use of diclofenac, and almost 96% of the patients had oral dosage forms of NSAIDs. The main indications of NSAIDs in these CKD cases were generalized body pain and joint pain. About 79% case of NSAID-induced CKD were serious, among which 54% led to the hospitalization and further use of NSAIDs discontinued in 86% of CKD cases.
CONCLUSION: The present study revealed that prolonged use of NSAIDs in chronic pain conditions was responsible for CKD. To reduce the risk of NSAIDs-induced CKD, health care professionals should take the necessary steps to improve patient safety.

 » Introduction Top

Nonsteroidal anti-inflammatory drugs (NSAIDs) are anti-inflammatory drugs and analgesics which are the most commonly used medications in the world. More than 30 million people are taking NSAIDs daily.[1] NSAIDs cause adverse effects like hyperkalemia, retention of sodium and water, acute kidney injury, nephritic syndrome, interstitial nephritis, papillary necrosis, and developmental effects.[2] Chronic kidney disease (CKD) is one of the most critical causes of morbidity and mortality in the world.[3] Hence, there is a significant risk of renal injuries/effect associated with the consumption of NSAIDs. Compared to other dosage forms like oral or topical of NSAIDs, parentral preparations of NSAIDS are having a high risk of the kidney.[4] Selective cyclooxygenase-2 (COX-2) inhibitors such as celecoxib and rofecoxibcause more renal failure compared to nonselective COX-2 inhibitors.[5] COX-2 selective NSAIDs are responsible for decreased glomerular filtration rate (GFR), increased serum creatinine, and hypertension.[6] High and cumulative dose of NSAID is responsible for CKD but not the standard dose.[5] NSAIDs like naproxen, celecoxib, meloxicam, nabumetone, and piroxicam having long half-life caused CKD.[7] Decreased renal blood flow, tubular obstruction, and cell-mediated immune injury is the main mechanism of NSAIDs induced chronic renal disease.[8] NSAID like phenacetin, which leads to papillary necrosis was banned from the Australia market.[9] Piroxicam and ketorolac are responsible for renal injury by affecting renal perfusion.[10] Long-term exposure of oxicams may cause CKD and analgesic nephropathy.[11] NSAID-induced chronic renal failure is arduous to diagnose because symptoms are not initially visible.[12] Several guidelines suggest avoiding NSAIDs in renal failure.[6] Even though 9%–13% of patients with CKD are still using NSAIDs.[13] The main reason for using NSAID in CKD patients is chronic pain, which further increases the risk of nephrotoxicity.[14] CKD patients, who discontinued NSAIDs, improved their renal function after 6 months.[14] NSAIDs interfere with the kidney's ability to auto regulate glomerular filtration pressure results in decrease in GFR and ultimately leads to kidney failure.[15] NSAIDs can produce inflammatory changes in the nephron parts and leading to fibrosis and renal scarring.[16] NSAIDs cause acute interstitial nephritis by acting as antigens, which stimulate immune reactions in the interstitium.[16] Chronic interstitial nephritis is caused by the use of high and extended dose of NSAIDs and occurs in patients with preexisting kidney disease.[17]

The widespread use of NSAIDs and a variety of deleterious effects on different organ systems prompted us to carry out this retrospective study of NSAIDs-induced CKD in the Indian population.

 » Materials and Methods Top

Individual case safety reports (ICSRs) reported to the Uppsala monitoring centre Pharmacovigilance database system “VigiLyze” was analyzed. VigiLyze is a useful online search and analysis tool that provides access to ICSRs in VigiBase, a global database, containing ICSRs from more than 131 World Health Organization (WHO) member countries. It consists of pharmacovigilance data on allopathic, herbals, as well as biological medicines, including vaccines. The Indian Pharmacopoeia Commission is working as National coordination centre under Pharmacovigilance Program of India (PvPI) and has authorized access to VigiLyze. It provides global, national and regional information of suspected adverse drug events and is particularly valuable in cases where there are limited data available. It allows comparisons between the global and national pharmacovigilance information related to particular available drugs. We collated and analyzed the ICSRs from VigiLyze using the preferred term “Chronic Kidney Disease” and “NSAIDs”from July 1, 2011 to September 12, 2019. We filtered out the 28ICSRs of NSAIDs associated CKD, which were analyzed with respect to age, sex, type of reporter, type of NSAIDs, route of administration, indication, the seriousness of reaction, and year of ICSRs collection.

About 82% of CKD cases due to NSAIDs were in the age group of 40–80 year [Figure 1]. In this age group, generally, people suffer from arthritic pain and other illness and possibly have taken NSAIDs for symptomatic relief. About 14% of ICSRs were <40 years of age and 4% >80 years. Males were more prone to NSAIDs-induced CKD in comparison to females group. About 54% of the patients with NSAID-induced CKD were males and 46% females [Figure 1]. According to the literature, females were reported to show renoprotective action due to estrogen compared to males, hence less affected than males.[18]

About 43% (12 ICSRs) of the patients got CKD due to the use of diclofenac, and 14% (4 ICSRs) of the patients got CKD due to ibuprofen [Figure 2]. Diclofenac and ibuprofen belong to nonselective COX inhibitors and could cause more adverse effects on the kidney in comparison to other selective COX inhibitors. The primary reason for the renal selectivity may be due to abnormal regulation of vasodilatation that occurs with these drugs, which is the main reason for NSAIDs-induced renal failure.

Out of the 28 suspected NSAIDs-CKD ICSRs, 8 had a combination of two different NSAIDs such as diclofenac along ibuprofen, aceclofenac along paracetamol, diclofenac along aceclofenac, paracetamol along tramadol, and paracetamol along diclofenac [Figure 2]. The patients, who took a combination of NSAIDs, would have further increase risk of nephrotoxicity due to additive or synergistic effect. In two NSAIDs-CKD ICSRs pantoprazole, dopamine, trihexyphenidyl were concomitant drugs along with NSAIDs.

Analysis of these 28 ICSRs associated with NSAIDs-CKD revealed that 96% of the patients used oral dosage forms, while only 4% of patients used parenteral dosage forms of NSAIDs. In general, for chronic pain conditions, prescribers prefer to give oral forms of NSAIDs compared to parenteral forms. Moreover, patients prefer to use over-the-counter pain killers in tablet form, which are easy to administer as well as more economical compared to other dosage forms. The indication for NSAIDs use is summarized in [Figure 3], and it revealed that 25% and 10.71% of patients are using NSAIDs for generalized body pain and joint pains, respectively. About 7.14% of patients used NSAIDS for migraine, acute pain and unspecified pain and remaining 3.57% of patients used NSAIDs for rheumatoid arthritis, myalgia, gout, fever, and arthralgia.

About 79% of suspected ICSRs of NSAIDs associated CKD were serious and remaining 21% nonserious [Figure 4]. According to WHO, there are six seriousness criteria of adverse drug reactions (ADRs), for example, suspected drugs lead to cause hospitalization or prolongation of hospitalization/death/life-threatening condition, disability, or other medically necessary condition. Fifty four percentage of NSAID-induced CKD ICSRs showed prolonged hospitalization or caused hospitalization of patients, 21% of ICSRs outcome was unknown, 14% of patients experienced life-threatening condition, 7% of patients had other medically important condition and 4% patients died [Figure 4].

After suspecting CKD due to NSAIDs, physician discontinued the suspected drug from the treatment regimen for preventing further risk. In 86% of ICSRs of NSAIDs associated CKD, after noticing the occurrence of ADR i.e., CKD, the NSAIDs were discontinued. In 7% of ICSRs action taken was unknown, action taken was not applicable in 4% and in 3% ICSRs doses were not changed [Figure 5]. The maximum reporting of suspected ICSRs of NSAIDs associated CKD were by the pharmacist (54%) followed by other healthcare professionals (32%) and physicians (14%) [Figure 5]. The highest contribution of ICSRs reporting by pharmacists is may be due to more interaction with the patient about the drug and its side effects; therefore, they have a better opportunity to report ADR to PvPI. The under-reporting of these ADR by physician might be due to lack of time or other reasons.

There was no significant rise in the number of NSAIDs-induced CKD ICSRs between the year 2012 and 2016, though, there was sharp and identical rise in the ICSRs in the year 2018 and 2019 [Figure 6]. We received one case in the year 2012 and 2013, two cases in the year 2014 and 2015, no case in the year 2016, 4 cases in the year 2017, 9 cases in the year 2018 and 2019. Although, the abrupt rise in the total number of NSAIDs-induced CKD ICSRs in the last 2 years reveals that healthcare professionals are more vigilant on pharmacovigilance for the sake of patient safety.

 » Discussion Top

ADR is the injurious and unintended reaction, which happens at the dose of drug usually used for prophylaxis, therapeutics, and the diagnosis of a disease. It grounds an enormous financial and societal distress on a nation due to the high incidence rate of morbidity and mortality. The postmarketing ADRs monitoring or postmarketing surveillance study of a drug is crucial because clinical trials conducted before the marketing authorization in the limited number and types of subjects.[19] Therefore, a drug, found safe in the clinical trial might produce serious ADRs in future. Hence, ADRs monitoring or pharmacovigilance is necessary for better health care.[19]

Most of the physicians would have prescribed NSAIDs as first-line treatment for any pain conditions making the patient use NSAIDs abundantly and become prone to ADRs and this became the base of our study.[20] The current pharmacovigilance study shows the risk of CKD associated with NSAIDs. All results are interpreted based on pharmacovigilance data analyzed through VigiLyze.

In this retrospective study, CKD was mostly observed in the population of 40–80 years old people, which shows similar results of the study conducted by Koshy et al.[21] They conducted a case-control study on the association between NSAIDs use and progression of CKD in elders and concluded that high cumulative doses of NSAIDs were associated with high risk of CKD. They analyzed the histo-pathological spectrum of kidney biopsies in the elderly population and mentioned NSAIDs were one of the causes of drug-induced tubule-interstitial nephritis. They stated that mostly the people of the mean age of 76 years had renal failure.[21]

The present study highlighted that CKD risk was slight higher in males than females, confirming the finding by Nitsch et al.[18] They conducted a meta-analysis study to assessed the relationship between gender and the risk of developing CKD and found that males have high-risk of mortality as compared to females.[18] Estrogen have a renoprotective effect in a rat model as reported by Seliger et al.[22]

In our study, diclofenac and aceclofenac were the leading cause to CKD, while Tan et al., reported indomethacin as the key cause of CKD.[23] They mentioned decreased renal function with indomethacin is due to concomitant diuretic use which caused volume depletion.[23] This difference might be due to the massive usage of indomethacin in comparison to diclofenac and aceclofenac during that period.

In our study, most NSAIDs responsible for CKD used in the oral dosage form, whereas, in the study conducted by Chang et al., showed that parenteral forms of NSAIDs have a higher risk of developing CKD rather than oral forms.[4] Here, author conducted a nationwide cross-over study to investigate the relationship between short-term use of NSAIDs and the development of end-stage renal disease. They found the highest adjusted odd ratio with parenteral forms compared to oral dosage forms.[4]

In our study, the use of NSAIDs leads to CKD, whereas, as per Go et al., use of NSAIDs leads to renal failure, cardiovascular side effects.[24] They conducted a systemic review to identify the risk of acute renal failure in patients with CKD in community settings. They concluded that absolute risk with NSAIDs is higher in elders with CKD.[24]

In our study, the main reason for NSAIDs use was generalized pain. In contrast, the study conducted by Wu et al., NSAIDs mostly used by the patient for chronic pain conditions.[14] They conducted cohort study to examine the relationship between chronic pain in CKD patients and the use of NSAIDs, they found NSAIDs use in CKD patients is very common even though it is against to guidelines.

In the present study, the kidney function of the patient, physicians mostly stopped the use of NSAIDs after observing the CKD, Zhang et a., made a similar recommendation.[25] Another study reported that there was a two-fold rise in the risk of kidney failure among individuals with lifetime use of more than 1000 paracetamol pills and eight-fold increased risk with a cumulative dose of more than 5000 NSAIDs pills.[26] Therefore, previous studies emphasized an association between NSAIDs and the risk of chronic renal failure.

In the present study, most of the ICSRs were received from health-care professionals, signifying that healthcare professionals were taking keen interest in monitoring and reporting of safety data of NSAIDs. Nowadays, the role of healthcare professionals in Pharmacovigilance is increasing. Pharmacists, nurse, and physicians have primary contact with patients, acquire a good knowledge of the drugs, therefore, can quickly identify and report adverse effects of drugs to the concerned authorities. The contribution of Pharmacists and health-care professionals in ADR reporting is clearly reflected.

 » Conclusion Top

We found that NSAIDs used by patients for chronic pain leads to CKD, males were more prone to CKD in compare to females, about 80% ICSRS were serious and lead to hospitalization in 54% of cases. Diclofenac contributes to more than half of cases of NSAIDs-induced CKD. To reduce risk with NSAIDs, health care professionals should take the necessary steps to improve patient safety like alternative pain management treatments, choosing drugs having relatively safer profile than drugs with high-risk, decreasing the dose of the drugs, regular monitoring of renal function tests and limiting the chronic use of NSAIDs. Although, the present study has some limitations such as lack of complete information in ICSRs, under-reporting or few number of reports and last but not the least all the ICSRs received on voluntary basis or as spontaneous report. Moreover, the present studies do not suggest any impending significant change in clinical/regulatory intervention of NSAIDs. However, a further focussed or active pharmacovigilance study will required to better evaluate the benefits and risk ratio related to the uses of NSAIDs.
